Graco 15A175 Spring Plate

Graco 15A175 Spring Plate – Detailed Overview

The Graco 15A175 Spring Plate is a precision-engineered component that provides a stable base for compression springs in Graco regulator and diaphragm assemblies. By evenly distributing spring forces, it maintains proper alignment and preload, ensuring consistent and reliable performance in fluid‑handling systems.

Compatible Applications

• Graco mechanical back-pressure regulators and pump assemblies using the 15A175 spring plate
• Diaphragm housing assemblies requiring spring support and correct preload
• Industrial spray, coating, adhesive, and dispensing systems with high-cycle spring mechanisms

Key Features & Benefits

• Even Force Distribution: Provides a flat, stable surface for springs, reducing stress and extending component life.
• Precise Alignment: Keeps springs properly aligned to prevent wear and ensure smooth operation.
• Durable Construction: OEM-specified materials resist deformation and withstand repeated compression cycles.
• Reliable Performance: Maintains spring preload for consistent regulator or pump function.
• OEM Quality Assurance: Manufactured to Graco standards for fit, durability, and performance.

Installation & Maintenance Tips

• Depressurize and isolate the system before disassembly.
• Inspect the spring plate for wear or deformation during rebuilds.
• Ensure the spring sits squarely on the plate to maintain proper alignment and preload.
• Clean all mating surfaces before reassembly to avoid uneven load distribution.
• Test the system after reassembly to verify correct spring function and performance stability.
